The incidence of residual PH was significantly higher in patients with persistent exercise intolerance (p 0.001). However, 27 out of 45 patients with persistent exercise intolerance had no residual PH. In the multivariate analysis, preoperative transfer factor for carbon monoxide (TLCO) was the only predictor of exercise intolerance after PEA.Conclusions The majority of CTEPH patients has exercise intolerance after PEA, often despite normalisation of resting hemodynamics. Not all exercise intolerance after PEA is explained by the presence of residual PH, and lower preoperative TLCO was a strong predictor of exercise intolerance 6 months after PEA.FootnotesThis manuscript has recently been accepted for publication in the European Respiratory Journal.
